 - Or use [OVHcloud Connect](https://www.ovhcloud.com/fr/network/ovhcloud-connect/) for low-latency and high bandwidth.
 
-### 9. Deploy Veeam Proxy Server
-- Set up a Veeam proxy on your on-prem infrastructure.
-- Verify connectivity with the Veeam B&R server in the HPC.
-- Follow the [proxy setup guide](https://helpcenter.veeam.com/docs/backup/vsphere/add_vmware_proxy.html?ver=120).
+### 9. Deploy Veeam proxy server
+
+Deploying a Veeam proxy server is essential for optimizing data transfer during replication. 
+
+Here’s how to set it up:
+  1. Open the Veeam Console and go to the **Backup Infrastructure**{.action} section.
+  2. In the inventory pane, click **Managed Servers**{.action}.
+  3. Add your on-prem proxy server (Windows or Linux) by selecting **Add Server**{.action} and following the wizard.
+  4. Once added, configure the server as a proxy by navigating to **Backup Proxies**{.action} and clicking **Add Proxy**{.action}.
+  5. Assign the necessary resources and settings (transport mode, maximum concurrent tasks, etc.).
+
+After configuring, verify the proxy server’s connectivity with the Veeam B&R server in your Hosted Private Cloud. 
+
+For a detailed walkthrough, check the [proxy setup guide](https://helpcenter.veeam.com/docs/backup/vsphere/add_vmware_proxy.html?ver=120).
+
+### 10. Create replication jobs
+
+To create a replication job in Veeam Backup & Replication:
+
+  1. Open the Veeam Console and navigate to the **Home** view.
+  2. In the inventory pane, click on **Replication Jobs**{.action}.
+  3. Select **Create Replication Job**{.action} from the menu.
+  4. Follow the wizard to:
+     - Add the VMs you want to replicate.
+     - Choose the target destination (your OVHcloud HPC).
+     - Configure settings like compression, throttling, or application-aware processing if needed.
+  5. Specify the schedule for the replication job.
 
-### 10. Create Replication Jobs
-- Use the Veeam B&R server to define replication jobs.
-- Follow the [replication job setup guide](https://helpcenter.veeam.com/docs/backup/vsphere/replica_job.html?ver=120).
+After completing the setup, save the job and run it to start replicating your VMs. 
 
-### 11. Start and Test Replication Jobs
-- Start replication jobs and monitor their progress.
-- Run a pre-test with Veeam’s failover function to check replication without affecting source VMs:
-  - [Failover process](https://helpcenter.veeam.com/docs/backup/vsphere/failover.html?ver=120)
-  - [Undo failover process](https://helpcenter.veeam.com/docs/backup/vsphere/undo_failover.html?ver=120)
+For detailed steps, check the [replication job setup guide](https://helpcenter.veeam.com/docs/backup/vsphere/replica_job.html?ver=120).
 
-### 12. Migrate Workloads
-- Perform a planned failover to turn off on-prem VMs, replicate any final changes, and power on the VMs in HPC.
-- Check the [planned failover guide](https://helpcenter.veeam.com/docs/backup/vsphere/planned_failover.html?ver=120).
+### 11. Start and test replication jobs
 
-### 13. Validate Applications and Services
+Once your replication jobs are set up, start them from the Veeam Console:
+  1. Open the **Home** view and navigate to **Replication Jobs**{.action}.
+  2. Select the job you created and click **Start**{.action} to begin replication.
+  3. Monitor the progress to ensure there are no errors.
+
+To test replication, use the **Failover Now** feature:
+  1. Open the **Replicas**{.action} section in the Veeam Console.
+  2. Right-click the replicated VM and select **Failover Now**{.action}.
+  3. Confirm the action to activate the replica without impacting the source VM.
+
+After testing, undo the failover:
+  1. Go back to the same replicated VM in the **Replicas** section.
+  2. Right-click and select **Undo Failover**{.action} to revert to the original state and resume replication.
+
+Testing ensures that your replicas are functional and ready for production use without affecting your on-prem environment. 
+
+For more details, refer to the [Failover process](https://helpcenter.veeam.com/docs/backup/vsphere/failover.html?ver=120) and [Undo failover process](https://helpcenter.veeam.com/docs/backup/vsphere/undo_failover.html?ver=120).
+### 12. Migrate workloads
+
+Use the **Planned Failover** process to migrate your workloads without losing data or disrupting services:
+  1. Open the Veeam Console and go to the **Home** view.
+  2. Navigate to the **Replicas** section and locate the VM replica you want to migrate.
+  3. Right-click the replica and select **Planned Failover**{.action}.
+  4. Confirm the action. Veeam will:
+     - Synchronize any final changes from the source VM to the replica.
+     - Power off the source VM automatically.
+     - Power on the replica in the target environment.
+
+Once the process completes, validate that the replica is active and functional in the Hosted Private Cloud. 
+
+For more details, refer to the [Planned Failover guide](https://helpcenter.veeam.com/docs/backup/vsphere/planned_failover.html?ver=120).
+
+
+### 13. Validate applications and services
 - Confirm VMs boot without issues.
 - Test connectivity to services like AD, DNS, and internet-facing apps.
 - Verify that all applications are working correctly.
 
-### 14. Confirm Permanent Failover
-- Finalize the migration by using the permanent failover action:
-  - [Permanent failover guide](https://helpcenter.veeam.com/docs/backup/vsphere/permanent_failover.html?ver=120).
+### 14. Confirm permanent failover
+
+- To make the replica VM your new production VM, open the Veeam Console and navigate to the **Home** view.
+- Click on **Replicas**{.action} in the inventory pane and find the replica VM you want to finalize.
+- Right-click the VM and select **Permanent Failover**{.action} from the menu.
+- Confirm the action when prompted.
+
+Once done, Veeam will remove the original VM from replication jobs and adjust the settings so the replica VM becomes the primary one. 
+
+For more details, check the [Permanent Failover guide](https://helpcenter.veeam.com/docs/backup/vsphere/permanent_failover.html?ver=120).
 
-### 15. Optimize and Secure Your Environment
+### 15. Optimize and secure your environment
 - Move VMs to the desired storage (e.g., vSAN or NFS datastores) using [Storage vMotion](https://help.ovhcloud.com/csm/fr-vmware-storage-vmotion?id=kb_article_view&sysparm_article=KB0046287).
 - Create backups for your workloads with OVHcloud S3 storage as described [here](https://help.ovhcloud.com/csm/fr-public-cloud-storage-s3-veeam?id=kb_article_view&sysparm_article=KB0047499).
